Specificalion forming of Letters Patent Nof 47,692. dated May 16. 1865.

panying drawing's, forming a part :of this specification', and in which-A Figure 1 represents a plan view of my in'- vention, the seat for the, driver being removed.

-Eig.-2- represents a longitudinal section online A B, Fig. 1, with the seat added. Figs. 3

and 4 represent a modification ,of part of ny.

lsaid invention. p 4

In the drawings, .P represents thetong'ue or draft-pole of the machine, therear end of which is fitted in a groove or recess cast in the top of the tongue-plate E, where it is held in any suita blemanner-onemodebeing showninthe draw;

ings, viz., by means of the s crews or bolts i i. (Shown in section, Fig. 2.) The tongueplate E extends' back of the tongue, and has a hole, c, forthe reception of the inain--axle ofthe ma-f chine, and back of thel hole e is a vertical hole,

f, for the receptionuof the seat-standard, as in.- dicated in Fig. 2. This tongue and seat plate is designed to be used upon that class of ;ma chines in which a. tilting` frame is combined with a hinged tongue, as Will be' readily understood by those 'skilled in the art of mowing-machines. It is particularly applicable to the class of machines known and patented as the *T* Union Mowing-Machine. YVhen the said invention is in use, the weight of the driver acts' as,l a counterpoise or balance to the tongue 'or draft-pole, and thus relieves the neeks of the horses fromthe weight thereof.

zThe 'main frame, to which the gearing and cutting apparatus are attached, is to be connected to the Vmain axle, so as to be free to confform to the inequalities'in the' surface of the: grmind;A If it shouldbe desired to have'thefi main a'Xle of theV frame move with the tonguepiece,th'en the, screw h 'is to be turnedup.. y In the latter 4case the axl'e of 'the'main frame' would' have to lbeso fitted as to turn loosely in .bearings or boxes on said frame. v

I Figs. 3'and 4. the designiis to have the frame suspendedto a shaft or axle passing throughv holes inhubs G .G,1a1id.the main aide,

to which the-main drive-wheels are attached,

through the holes in hubs H H, and the seat i- 'for the driver be 'supporteduponthearms which connect the hubs G Grand H H. -`By the latter arrangement some .slight motion would be communicated to the main frame .by the tilting or rocking motion of' the tongue, 4

and I prefer the plan first above described by reason thereofl The -seat J is attached to a standard, K, whereby it can be adjusted by means of 'the setfscrewg at'any desired height;

It is not deemed necessary to 'describe or illustrate the various parts oi a moWing-maf chine, 'as those 'skilled in the art Will understand the application of my said invention.

What I claim, and desire to secure'by Letters Patent, is- The u'se'of the socket f, cast with the poleplate, in. combination With the adjustable standard K, forsupporting and adjusting lthe seat,`substantially as herein described.
